What these specs mean in practice

Dynamic Load Rating: 40.5 kN (9,105 lbf). Static Load Rating: 24.0 kN (5,395 lbf). Rotational Speed, Maximum: 3,550 RPM on grease. Operating Temperature Range: −40 to 120 °C (−40 to 250 °F). Item Weight: 3.200 kg (7.06 lb). The spherical outer ring takes up initial shaft misalignment at mounting, so the two base bolts can be tightened against a shaft line that is not perfectly parallel to the mounting surface.

Relubrication

Relubrication Feature: Outer ring relubricatable. Grease enters through the housing fitting and passes into the insert through the outer ring, reaching the ball track directly.
